Dispersive Delay Lines

Dispersive delay lines historically evolved as matched filters for linear fm waveforms in military radar pulse expansion and compression systems. Today, with Andersen's SAW and IMCON technology, a large range of parameters are available which make possible new approaches to signal processing. In addition to expanding the performance of radar pulse expansion and compression systems, Andersen's dispersive delay lines provide new capabilities in spectrum analysis, variable delay systems and adaptive bandpass filtering systems. Because of the low cost high volume production benefits of the SAW technology, dispersive delay lines are now available at costs compatible with commercial solid state radars.
